Specification of Letters Patent.

Patented April 28, 1908.

Application filed August 30, 1907. A Serial No. 390,797.

To all whom 'it 'may concern:

Be it known that I, WILLIAM H. CONNELL, residing atPittsburg, in thecounty'of Allegheny on opposite sides of a partition, which in`some'cases was adapted-to be melted and become. 1ncorporated with the inot andin some cases the partition was wit drawn before the metalssolidified. Another method` of producing com ound ingots consisted oflcasting one body o metal and while that was lin ahighly-heatedcondition, teeming the Y second ,Iiody of me`ta1 thereunto.

these methods have been'practically success- None of ful, by reason ofthe fact that the line of delmarcation between the two metals wassharpand distinct and in no case was there a merging or intermingling ofthe two bodies, so as to form an integral mass having one qiuality onone face and a different quality or klnd on the opposite face.

-The invention described herein has for its object the bringing to etherof two bodies of metal while in `a mo ten condition under suchconditions that the metal of the two bodies will intermingle in theinterior of the' ingot, but will-maintain their distinct characteristicsat 'opposite sides of the ingot.

' The inventlon is hereinafter more fully de- 'scribed and claimed.

ed for the practiceof my In the accompanying'drawing forming a part ofthis specification", Figure 1- is a'lsec'- tional elevation of a form ofapparatus adaptinvention; Fig. 2 is a .plan view of a suitable form orconstruction of ladle and-Fig..3 is a plan view of al mold having thedeflector in position thereon.

In the practice of myinvent'ionthe two kinds or qualities aresimultaneously teemed into the mold, care bein taken that the twostreams of metal shal not intermingle. Preferably the two vstreamsshould be separated as widely as ossiblewhile owing into the mold, andthe ilbwing together of the two lnetals will take place only after theinflowing streams have reached the-bottom of the mold or the metal"previously formed. I have found that when two bodies ofmetal and Stateof Pennsylvania, a citizen of the United States, have invented or dis-Aform of apparatus `of the outlets or are -thus lbrought together in amold there will -be sufficient agitation to cat l'se a thoroughcommingling of the metals 1n the interior' of the ingot, and that themetals will be commingled in approximatelyequal' ortlons in and adjacentto a certain plane, )ut that the percentage will change onopposite'sidcs of s-uch plane,-that is the percentage of one metal willdecrease and that the other will increase from such tothe sides`ofthe/ing'ot, where only one metal will be found. In an ingot cast inthis manner no plane of cleavage will be'formed, .but one metal will befound on one side of theingot and will gradually decrease in uantityvtowards the other side, while the ot er metal will correspondinglyincrease, thus avoiding lsharply defined zones.

In the drawing I have shown a convenient for the practice of my method,v`bul'l as regards the broad terms of the claims the inventionis notlimited to such apparatus, since other means `will readil suggestthemselves to those skilledin the art lfor carrying out my improvement.

ments or chambers A and B, each provided with outlet openings 2, adaptedto be controlled by plugs 3. As both ports should be openedsimultaneouslythe plugs are 4connected to acommonloperatinglever4.Whenit is desired to produce ingots in which the proportions of thetwo'metals vary, provision should be made, either by varying the sizesthe movement of the plugs, so that the flow ofthe metals will yary withthe proportions desired -in the ingot. It will be understood that'compartments' and ports in the'ladle may opposite sides of the ingot.But 1t 1s preferred that the stream of'metalshouh be .80 The. ladle 1 isdivided into two'compartbe so arranged that the v streams of metal willflow closely adjacent to s read out, and-to-'that end I employ de- 4ecting plates 5 and 6 which are supported on the ingot mold. As thestreams of metal strike these plates, they are spread out and deflectedtowards opposite sides of the mold. When these flat streams strike thebottom of the moldsor metal contained therein, they will flow laterallyand meet in a plane `the position of which will vary in accordance withthe relative volumes of the Ymetals.' l It is characteristic of myimproved method that the two streams of metal are kept separate anddistinct one from the other, and that the metals commingle only whenthey move in directions' at an angle to the original direction-of thestreams.

In lieu of tcp teeming, bottom casting may be em loyed the metalsentering the mold throug the bottom in separate streams and preferablyat points adjacent to oppo-` site sides of the mold, so as to avoid anycommingling of the metals except by a flow thereofina direction at anangle tothe line `or direction of iiow at the time they enter the mold.

I claim herein as my invention:

l. As an improvement in the art of making compound ingots, the methodherein described which consists in teeming metals difscribed Whichconsists in simultaneously introducing metals varying in one or morecharacteristics into the' mold in distinct streams side by side andpermitting the metals to move laterally in Aopposite directions andintermingle in the zone of meeting or junction.

3. an improvement in the art of'making compound lngots7 the methodherein described which consists in simultaneously ouring the metals intothe mold in streams aving volumes proportional to the relativequantities of the metals desired in the iinished ingot, and kee ing thestreams separate and distinct whl e moving in a vertical direction.

In testimony whereof', I have hereunto set my hand..

WILLIAM H. CON NELL.
